'DRIVING-AXLE BOX FOR LOCOIVIOTIVES.

To all whom t may concern Be it known that I, KENNETH RUsHToN, a citizen ofthe UnitedStates, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Driving- Axle Boxes for Locomotives, of which the followin g is a specification.

My invention is particularly adapted for use in connection with the axles of the driving wheels of locomotives which require a heavy and substantial box and which must properly support the springs which, in turn, carry the frame of the locomotive.

`One object ofl my invention is to construct a single box for each axle, the box extending from one side frame to the other and having the proper extended-bearing for the axle.

A further object of the invention is to construct the box so that the spring supporting the frame can be mounted thereon so as to clear the frame and to support the springs In the accompanying drawings z-Figure 1, is a transverse sectional view through the frame of a locomotive on the line a-a, Fig. 3, illustrating my improved axle box; Fig. 2, is a sectional plan view on the line b-b, Fig. 3, showing thebox in section; Fig. 3, isa side view with the axle in section and the driving wheel omitted; and Figs. 4 and 5, are views illustrating,modifications of the invention.

Referring to the drawings, 1, 1 are the two side frames of the locomotive, made in the ordinary manner.

2 is the axle on which are secured the drivingr wheels 3. The frame 1 has pedesl tals 4.

5 is the axle box which is mounted in the pedestals. This axle box isv made in one piece and extends from one side frame to the other, being arranged to slide between the pedestals 4:. In the present instance, there are liners 6 between the pedestals and the box. The box is flanged at 7 so as to hold it against longitudinal movement. Mounted within the box are vthe usual brasses or bearings 8,and the lower portion of the box has the well 9' of any suitable type secured in place by bolts or other fastenings This construction may bemodif 11, 11 are two springs mounted on a supl vport 1 2 `carried by the -box 5 and theselframes.

springs are properly located directly above elements of the equalizing gear. the spring support is located in linewith the frame/and straddles the frame, and, in this instance, the spring support can rest on the axle at any point throughout its length and be properly balanced and supported.

lVhile -I prefer to construct the spring support in the manner shown in l, it may be modified without departing from the essential features of the invention. For instance, in Fig.4, I have shown an independent support 12a at each side of the locomotive made in inverted U-shaped form so as to straddle the frame and support the spring ll directly above it.

In Fig. 5, I have illustrated another modi` iication where the spring 11 is not directly over the frame 1, as in Fig. 1, and, in this instance, I preferably use two independent double U-shaped spring supports l2". One of the U-shaped sections extends over the frame l and the other is locatedbetween the The spring supports at each side are made independent, but they may be connected, as illustrated in Fig. 1, if desired.

The vmain feature of the invention is mala ing the axle box in one piece extending from one side of the locomotive to the other and having extended bearingsrtherein for the axle, and sov arranged that the spring support may be located on the axle box at any point desired.

When it is necessary to4 remove the axle box from the frame of the locomotive, all that is necessary is to remove the lower retaining bar or plate 15 and either jack up the locomotive frame or lower the axle with the box clear of tlie frame, -in the ordinary manner.

My improved box will lit any of the standard frames and can be substituted for any of the ordinary boxes of the present construction. The weight of the spring Vis evenly distributed over the entire length ofl the journals. f

It will be understood that the bearing may be reinforced -by ribs, as shown in Figs.

1 and 2, in any manner desired, or it may lOl frames l and rest on the box 5, and has 'laterally extending brackets 13 Which project over the frames l and carry the-springs l1, but, asv stated above, this construction may be Inodiiied Without departing from the main features-of the invention.

I claim :-V p 1. The combination of the tWo side frames of a locomotive, each ,side frame having a pedestal; an axley box extending from one f side frame of the locomotive vto the other` and mounted in both frames and made as a unitary structure; springs above the side frames; and a spring support for said springs resting on the axle box.

2. The combination of the two side frames of a locomotive, each having a pedestal; 'an

axle box lextending from one side of the locomotive to the other and mounted in the box, said box being made as a unitary structure; springs mounted above the frames;4

and a' spring support ha-ving brackets sel
